Flush Valve Toilet

ABSTRACT

A flush toilet that includes an air reservoir having an interior diaphragm installed inside a tank in the toilet. The air reservoir has a hydraulic pressure maintained by a water supply coming from a conduit. At least two propulsion jets are located in a bottom portion of a toilet bowl. These propulsion jets are capable of ejecting contents of the bowl into a siphon upon activation of a flush mechanism. Furthermore, a double water-supply pipe system is located between a valve and the tank. The double water-supply pipe system includes a first pipe that extends from the valve to orifices in the bottom of the toilet bowl. A second pipe is connected at substantially 90° to the first pipe and extends from the first pipe to a rim of the toilet bowl.

FIELD OF THE INVENTION

This invention pertains to plumbing fixtures in general and, more particularly to flush toilets.

BACKGROUND OF THE INVENTION

Global potable water resources are gradually diminishing in spite of restrictions imposed by some countries that are intended to maintain these resources. The reduction in water levels in lakes, rivers, and the water table getting lower is troubling to all nations and it is desirous that this reduction be slowed. In North American households, 45% of all potable water used is consumed by our conventional toilets. Americans use up 50,000 liters of potable water to evacuate 600 liters of waste, a ratio of 83% (source ECONOWATCH USA.). Specialized organizations have affirmed that 5 billion liters of potable water are used in the USA every day.

Thus, it is desirable to manufacture and use toilets that are more sanitary and secure in the manner in which they are bolted to the floor. It is further desirable to manufacture and use a toilet having a superior flushing performance which on average reduces the amount of water consumed. These improved toilets may be installed on any conventional floor attachment base, and can be connected to the same water supply piping system to which conventional toilets are connected.

Approximately 80% of our conventional toilets lose water 24 hours a day because the flap gate located in the reservoir of conventional toilets only close by gravity without any pressure. Thus, when the flap gates are improperly closed, there is a flow of water which is not visible to most users because the piping between the supply tank and the toilet bowl are internal.

It is therefore desirous to produce a new valve (flushometer) for toilets. The new value includes a flexible diaphragm covering the flush evacuation conduit and is held in place by the water supply pressure. This inventive method of maintaining the diaphragm closed substantially reduces or eliminates the loss of water due from the toilet tank that has previously occurred between flushes. It is further desirable that the a toilet having the ability to reduce extraneous water loss be at least one of a floor mounted toilet and a wall mounted toilet.

BRIEF SUMMARY OF THE INVENTION

An object of the present invention is to provide a flush toilet that includes an air reservoir having an interior diaphragm installed inside a tank in the toilet. The air reservoir has a hydraulic pressure maintained by a water supply coming from a conduit. At least two propulsion jets are located in a bottom portion of a toilet bowl. These propulsion jets are capable of ejecting contents of the bowl into a siphon upon activation of a flush mechanism. Furthermore, a double water-supply pipe system is located between a valve and the tank. The double water-supply pipe system includes a first pipe that extends from the valve to orifices in the bottom of the toilet bowl. A second pipe is connected at substantially 90° to the first pipe and extends from the first pipe to a rim of the toilet bowl.

Another object of the present invention is to provide a system for hanging a toilet onto a wall. The hanging system includes a plurality of hangers attached to the toilet and connected to the wall. A removable toilet lid is mounted to the wall, the removable lid having a top that is held in place by a flat hook secured to the wall, and a bottom that is secured to the toilet. A drain acts as a conduit between a toilet siphon, otherwise known as a P-Trap, and a sewer line. The drain is secured to the siphon which is equipped with a sealing cushion.
